If you have ever used google Analytics for your website you may have come across an annoying quirk that hides the full referring URL when viewing “Traffic Sources”. Only the domain itself is shown which becomes an issue if you are trying to track down visitors being refered from a forum / blog post or similar. Fortunately this can be easily resolved by adding a custom filter in Google Analytics. Please follow the instructions below to setup the filter.
1) Login to your Google Analytics profile and edit profile
2) Add a custom filer.
3) Add custom Profile with the following settings.
Field A -> Extract A – Referral (.*)
Field B -> Extract B – (Leave Blank)
Output To -> Constructor – User Defined $A1
4) To view the report go to Visitors –> User-defined
Unfortunately the filter will only apply to new traffic so it will show (not set) until new traffic data comes in.
